The first Earth Day was celebrated in 1970, the year the Environmental Protection Agency was created. Endangered species, wild rivers, and scarce water resources all became issues of government concern, as did the cleanup of toxic chemical sites. Environmentalists in the 1980s and 1990s alerted the nation to further resource shortages and potential threats to Earth's welfare.
